Im pretty sure this is the lowest term.
The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse.
If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.
"<span>two angles are complementary;" that means the sum of two angles is 90. Since the sum of all three is 180, the last angle is 90. It is a right triangle.
"</span><span>two angles have equal measure;" we can't have two angles which are 90, so the other two are equal. But they sum to 90, so what number plus itself is 90? 45+45=90. We know now that the triangle has measures 45, 45, and 90.
We know that the legs of the triangle are the same, so we can use the Pythagorean theorem to show that </span>

, where h is the length of the hypotenuse and l is the length of the legs.
Of course, this means

. But "<span>the shortest side is half the length of the longest side</span>"! No triangles like this exist.
The only true statement is D
Answer:
1:5
Step-by-step explanation:
Their is 2 red pens, because 20(pens) - 8(blue pens) = 12(pens [blue excluded]) and there are 10 black pens (12 - 10 = 2)
So we can get an un-simplified ratio of 2:10, however in the list of answers you gave us:
Their is no 2:10, so now we need to simplify our ratio by dividing both 2 and 10 by 2, 2 divided by 2 = 1 and 10 divided by 2 = 5. As we can now see this gives us the ratio of 1:5 which is our second answer choice, and therefore since 1:5 is equal to 2:10 our answer is 1:5
Better labeling so I can understand.
